A vintage NASA-commissioned Rick Guidice painting gives a cutaway view of the inside of a space colony design known as the Stanford torus, a proposed habitat that would house 10,000 to 140,000 permanent residents. The rotating, doughnut-shaped ring could have a diameter of around 2 kilometers, revolving once per minute to give about 1.0g of artificial gravity on the inside of the ring through centripetal force. A massive system of mirrors would provide the sunlight needed for daily activity, agriculture, and so forth. (NASA Ames Research Center)

ChongQing, Sichuan Province is also knows as Chicago on Yangtze.

Enormously high bridges forming mazes over the city give an image to ChongQing as a city of future. 

Tomorrow is my second trip to the city. Bridges and unique architecture of houses will be my main goal.
